Chris You need to get them exactly all the same length or the frame will be twist when you tighten things up. Best way is to use a back stop. Stew |

OK - so if I make a little jig with a 6mm hole, push the jig up to lock up against the back of the chuck and then insert a pillar. Take it down to a perfect size, lock up the saddle and repeat with each of the pillar? I`ll let you know how it goes. They currently measure 45.00, 45.20 and 45.20 so they are not exact. EDIT: I was just reading this: http://madmodder.net/index.php?topic=1649.15 and unfortunately that would work as the critical size is shoulder to shoulder not end to end. |
| sbwhart:
Thats correct Chris shoulder to shoulder is the critical feature, your little jig idea would be just the ticket. :thumbup: Have fun Stew |
| raynerd:
something like this: Will it be accurate enough when repositioning each pillar as I will need to remove the jig from the jaws to unbolt it, or I could try and leave it in place and use a long screwdriver on my mini lathe? If I punch the jog to locate jaw 1 would that be good enough? |
| raynerd:
... it may be as accurate turning between centres and measuring them as I go and taking my time?? I`ll give it a think before I do anything, they are easy enough to make but wouldn`t like to waste my time for the sake of it. Chris |
